I slept with one partner between 1/22/14 and 1/24/14. I slept with someone else on a regular basis starting after 02/08/14 and on. This week I am 24 weeks pregnant. I had an ultrasound on 03/20/14 that said I was 6 weeks and 1 day. Is there any chance the baby was conceived between 01/22/14 and 01/24/14?

When was your last period and/or when is your due date?

I have gotten two due dates: 11/05 and 11/12. 11/12 was when the doctor took into account that my cycle is 35 days, instead of using standing 28 days calculation. I know for sure I had my period between 01/30 and 02/02. Im so freaked out though that I am starting to wonder if it was a regular period. AHHH! Please help!

Truth told, conception is an inexact science. It is all based on a mathematical calculation. Ultrasounds can be fairly accurate as the organs of the baby tend to grow at certain times during gestation.

Using my gestation wheel, the same one your doctor uses to determine your due date, it appears that you conceived somewhere around February 11. With that said, again it is an inexact science and with the dates of your encounters so close, you will have to have a paternity test after the baby is born to determine, without a doubt, who the father is.

It is possible that it could be either. As noted, dating is not exact.. so, they can not tell even the exact week, and never an exact day.

This is close enough, that it is possible. It is best to get a DNA test to verify.
